.To all whom it maycortc'arnhf 1 Be it known thatl, HOWARDrI-I. GRAY, a

citizen of the UnitedStat'es, residing at Hunt-.-

in gton, in the countyofzl-Iuntin'gton and State of Indiana, have 'lllVGIlliQQiDWtDd' useful. Improvements in Lawn-Sprinklers, of which i the following is a specification.

My invention relatesto improvements in.

lawn-sprinklers, and pertains to a sprinkler provided with improved means .wherebyjthe water from the hose causes the rotation ofa propeller-wheel, whereby a nozzlecarrying member is automatically directed at all points of a circleand at'thesame time raised and lowered. I ,1

In the accompanying drawings, Figure 1 is a side elevation of a sprinkler embodying my" invention.

plan view. Fig. 3. is

Fig.2 is an enlarged inverted a detached view of the hose-clamp.

Referringnow tothe drawings, 1 indicates an annular supporting member or ring which is provided atitsimder side with a plurality of leg-supporting sockets 2,'in.which the s'up-, porting-legs 3 are securely attached. The inner edge of this supporting-ringl. is cut out, as shown at 4, for thepurposeof form ing a supporting annular shouldered recess for the innerrotatable ring 5. Theperiphery of the supporting-ring 1 is providedtwith cogs 6, and through the medium ofwa'mechg anism, to beihereinafter described,the.inrier ring 5 is revolved. .1

A suitable supporting frame or Web 7 is car; ried bythe inner'ring ,5, and jojurnaled ;in. this frameor webis a wheel 8. This-wheel 8 has its edgeor periphery provided with a worm-gear 9, adapted to mesh withthecogs 6 of the outersu'pporting annular member or ring 1, the inner'or revoluble ring or member 5bei-ng cutout, as shown at 1,0, to per-f mit the said worm of the said cogs.

A revoluble shaft ll is/supported in a suit 5o bers and has connected therewith a suitable stationary outer supporting-ring 1. the wheel 8 to'engage- 1ower..por.tion.or endof .the revoluble shaft ll carrie's a suitable.;.worm 16, which is in 'mesh'with laterallyprojecting cogs 17 upon oneifacetor'sideof the wheel 8.

A nozzle-supporting member 20 is centrally pivoted to the supportingfframe 7 of the inner ring 5 through the medium of a centrally- -arranged bolt 21, the; said bolt being sufficiently loose to permit an oscillation of the said nozzle-clamp. The nozzle-clamp is so constructed that while the nozzle is supported it will permit it to turn therein as the inner revoluble ring 5 is rotated, and thus prevent a winding or. twisting of the-hose.

A cam or eccentric 22 is formed as a part of or rigidly connected with the wheel 8, and thiscam or eccentric"- is connected with the nozzle-clamp for the purpose of oscillating it, and hence automatically lowering the out.- let end thereof, thus changing the range of 'water-throwsfrom themaximum to the minimum distance, which thoroughly waters all points .within the range of, throw-which depends upon "thefwater-pressu-re', astis well understood, r

Inoperationthe, machine is supported by the legs ,3, which, astbefo're stated,1are connectedwith theouter annular member or ring 1 anduthe nozzle ofr the'ho'seconnected with Theirevolution of the wheel 8 causes the an- Y nular ring5 to revolve by reason of the engagement of the worm 9 with thecogs 6"0f the H Therefore'the-wheel Stravelsaround with the annular ring 5 and carries with it the hose-clamp 20, which is attached to the annular'ring ata point to one side of its axis, which,';.tog'ether with the cam or eccentricaction,causes the water to be directed automatica'llyito all points of a circle and the nozzlesiiiiultaneously raised and lowered. The ring 5, which carries the nozzle support, travels around comparatively slow, while at the same time the exit end of the nozzle is being raised and lowered.

By means of a sprinkler constructed as herein shown and described I am enabled to cover a very large area sufficient to represent an ordinary lawn and at the same time to cover completely the space between the extreme point of throw andthe sprinkler itself, thus thoroughly and equally watering the area within the range of water-throw from the nozzle.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A sprinkler comprising an annular supporting-frame, a rotatable frame supported thereby, a propeller-wheel supported by said rotatable frame, an intermediately-pivoted hose supporting clamp adapted to travel around said propeller-wheel, and means carried by the rotatable frame for oscillating said hose-clamp, substantially as described.

2. A sprinkler comprising an annular supporting-frame, cogs carried by the inner periphery of said supporting-frame, a rotatable frame mounted therein, a centrally-located vertical shaft carried by said rotatable frame, a worm-gear carried by the rotatable frame and driven by said shaft and meshing'with the gear on the supporting-frame, a propellerwheel carried by the upper end of said shaft, and a hose-clamp carried by said rotatable frame and adapted to travel around said propeller-shaft, substantially as described.

3. A sprinkler comprising an annular stationary member having cogs upon its inner periphery, a revoluble member carrying a worm-gear in engagement with the said cogs, a revoluble shaft being operatively connected with the worm gear, substantially as described.

4. A sprinkler comprising an annular horizontal stationary member having cogs upon its inner periphery, an annular revoluble member supported thereby, a worm-gear carried by the revoluble member, a verticallyarranged shaft supported by the revoluble member, a propelling member connected with the said shaft, the shaft and worm-gear being operatively connected, and the worm-gear in engagement with the said cogs, of the stationary annular member, and a nozzle or hose support, substantially as described.

5. A sprinkler comprising an annular horizontal stationary member having cogs upon its inner periphery, a circular horizontal revoluble member supported thereby, a vertically-arranged worm-gear carried by the revoluble member and meshing with the said cogs, a vertically-arranged revoluble shaft carried by the revoluble member and having a worm-gear in engagement with the said vertically-arranged wheels, a propeller-wheel attached to said shaft, and an eccentrically-arranged hose clamp or support carried by the member, a worm-gear in engagement with the supporting-frame, means carried by one side of said worm-gear by means of which it is driven, a hose-supporting clamp carried by said member, and means carried by the opposite side of said worm-gear for oscillating said hose-clamp, substantially as described.

8. A sprinkler comprising an annular sup porting member, a revoluble member, a wheel journaled therein and having aworm, engaging cogs formed upon the inner periphery of the annular member, a vertically-arranged shaft carrying a worm in engagement with said cogs carried by the side of said wheel, a propeller-Wheel carried by the upper end of said shaft, a hose-clamping member pivotally connected to said revoluble frame, and an eccentric connected to the side of said wheel and connected to the hoseclamping member, substantially as described.

9. A sprinkler comprising an annular horizontal stationary member having cogs upon its inner periphery, a circular horizontal revoluble member supported thereby, a vertically-arranged wheel carried by the revoluble member and having a worm-gear meshing with the said cogs, a vertically-arranged revoluble shaft carried by the revoluble member and having a worm-gear in engagement with the cogs carried by one side of said vertically-arranged wheel, a propeller-wheel attached to the upper end of said shaft, an cecentrically-arranged pivoted hose-clamp, and an eccentric carried [by the opposite side of said vertically-arranged wheel and connected to the said hose=clamp, substantially as described.

10. A sprinkler comprising a supportingframe, a rotatable frame supported thereby, a propeller-wheel carried by the rotatable member, an intermediate pivoted hose-clamp, and means operated by the propeller-wheel for revolving the rotatable member and oscillating said hose-clamp, substantially as described.

11. A sprinkler comprising an annular supporting-frame, a rotatable member supported thereby, a centrally-located propeller-Wheel carried by the said rotatable member, means rgo operated by'the saidwheel for-engaging the In testimony whereof I have hereunto set inner periphery .of the stationary member my-hand in the presenceof two subscribing and rotating the revoluble member, an inwitnesses.
